Bulk physical properties are needed to make sense of these observations and exploit them to constrain conditions in the protoplanetary disk where they formed. The key to obtaining bulk properties of transneptunian objects is that a sizeable proportion of them are binaries. Binary mutual orbits provide dynamical masses that can in turn be used to compute bulk densities, and a statistical sample of binary orbits offers powerful constraints on formation mechanisms as well as subsequent evolution. This proposal seeks to continue a multi-year campaign to obtain orbits for as large of a sample of binary transneptunian objects as possible. We seek to make efficient use of HST by targeting only the systems where we can obtain a dramatic improvement in orbital knowledge from just one or two visits, and only those where the secondary is too faint to pursue with ground-based near-IR adaptive optics techniques. OBSERVING DESCRIPTION The goal of this project is to image six kuiper belt binary systems at strategic times for purposes of determining their mutual orbits. All of these systems have been observed before, so only one or two more epochs are needed to secure their orbits. ADDITIONAL COMMENTS In the case of systems that need two visits, the second visit is marked as being on hold. The point of this is to wait until the results of the first visit are available and processed in order to determine optimal time windows for the second visit. 2 Solar System Targets Patterns Visit Proposal 13404 - Visit 01 - Mutual Orbits and Physical Properties of Binary Transneptunian Objects Proposal 13404, Visit 01, completed Wed Dec 18 02:48:08 GMT 2013 Diagnostic Status: No Diagnostics Scientific Instruments: WFC3/UVIS Special Requirements: BETWEEN 01-JUL-2013:00:00:00 AND 01-MAR-2014:00:00:00 Comments: A loose BETWEEN constraint is imposed on this first visit to target 1 to encourage observation before the main visibility window in spring 2014.

I haven't bothered to specify BETWEEN constraints for the lesser opportunities outside the main window, but could do so if these three opportunities look like an overbooked time for the telescope. # Primary Pattern Secondary Pattern Exposures (1) Pattern Type=LINE Coordinate Frame=POS-TARG (1), (2), (3), (4) Purpose=DITHER Pattern Orientation=46.84 Number Of Points=2 Angle Between Sides= Point Spacing=0.145 Center Pattern=false Line Spacing= # Name Level 1 Level 2 Level 3 Window Ephem Center (5) 2003QW111 TYPE=ASTEROID,A=43.6268524040 EARTH 00,E=0.114301015500,I=2.666342476 900,O=68.53067456800,W=21.218903 966000,M=273.089689410000,EQUIN OX=J2000,EPOCH=23-MAY2014:00:00:00,EpochTimeScale=UTC Exposures # 1 2 3 4 Label Target (5) 2003QW111 (5) 2003QW111 (5) 2003QW111 (5) 2003QW111 Config,Mode,Aperture WFC3/UVIS, ACCUM, UVIS2-C512C-SUB WFC3/UVIS, ACCUM, UVIS2-C512C-SUB WFC3/UVIS, ACCUM, UVIS2-C512C-SUB WFC3/UVIS, ACCUM, UVIS2-C512C-SUB Spectral Els.
